MNU: UndefinedObject(Object)>>doesNotUnderstand: #compareStates

[GoogleCodeExporter]

What steps will reproduce the problem?

Code:

(var count := [1])
(machine m
    (state o)
    (state t (onentry [count value: count value +1]))
    (eps o -> t ot)
    (eps t -> o to)
    )
(spawn m o)

Delete the code, then add

(machine p)

What is the expected output? What do you see instead?

MNU + an error saying machine m is not found. Note that if the interpreter is 
paused before deleting and adding, the error appears when the interpreter is 
unpaused.

Please use labels and text to provide additional information.

I've added a failing test case in commit LiveRobotics-Tests-johanfabry.9 There 
are actually 2 fails in the test case: first the mainmachine is not set right, 
and if that assert is commented out you get the DNU.

BTW, if you delete the running machine, then the program will restart. So, if 
you add a new machine without a spawn statement, the new machine will not be 
the 'active one' until you spawn your new program again with the new definition
